* Fix check for empty locale string in newlocaleCorinna Vinschen2016-10-221-2/+5
| | | | | | | | | | | | | | | The original test is broken. It tests for a NULL locale which isn't just wrong, it simply can't occur at this point due to an earlier check for a NULL locale string. Thus, the locale info for a category is never taken from the environment. Fixes Coverty CID 153467. Also, add comment. Also, add some parens for readability.

* Add _PC_CASE_INSENSITIVE to [f]pathconfKen Brown2016-10-215-1/+10
| | | | | | | | Update the getconf utility to support the new flag as well as _PC_POSIX_PERMISSIONS and _PC_POSIX_SECURITY. These were previously unsupported, probably as an oversight. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Don't check directories always case-insensitive in rename(2)Corinna Vinschen2016-10-192-1/+4
| | | | | | | | | | | | | | | | | | Long-standing problem in one of the corner cases of rename(2): If we rename a directory a check is performed to see if newpath is identical to oldpath or a subdir of oldpath. This check is (accidentally? no hints anywhere in ChangeLogs or code) performed case-insensitive for as long as we use Unicode paths and NT functions. This leads to the problems described in https://cygwin.com/ml/cygwin/2016-09/msg00264.html Change this to be conditional case-sensitive as all other checks but let's take this with a grain of salt. There may be corner-cases in this corner-case which require to chek parts of the path always case-insensitive. Off the top of my head I can't construct such a case but that's no proof they don't exist :} Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Fix regression in console charset handlingCorinna Vinschen2016-10-191-0/+2
| | | | | | | | | | | | Commit d16a5630 dropped usage of cygheap's locale functions in favor of local on-the-fly usage of UTF-8 instead of ASCII. This allowed to use the current local rather than a fixed system-wide locale set at startup time. d16a5630 just missed to add the ASCII->UTF-8 conversion in the console as well.

* Make ctype_.c and ctype_.h agree on _ctype_b typeThomas Preud'homme2016-10-171-0/+4
| | | | | | | | _ctype_b is defined in ctype_.c as a const char array for non cygwin targets allowing negative ctype index but as a char array for the same targets in ctype_.h, giving type conflict at compile time. This is because the cygwin targets are not treated specially in the latter file. This patch adds the necessary logic for cygwin targets in ctype_.h.

* dlopen (pathfinder): try each basename per dirMichael Haubenwallner2016-09-081-6/+6
| | | | | | | Rather than searching all search dirs per one basename, search for all basenames within per one search dir. pathfinder.h (check_path_access): Interchange dir- and basename-loops.
* dlopen: switch to new pathfinder classMichael Haubenwallner2016-09-083-109/+782
| | | | | | | | | | | | Instead of find_exec, without changing behaviour use new pathfinder class with new allocator_interface around tmp_pathbuf and new vstrlist class. * pathfinder.h (pathfinder): New file. * vstrlist.h (allocator_interface, allocated_type, vstrlist): New file. * dlfcn.cc (dlopen): Avoid redundant GetModuleHandleExW with RTLD_NOLOAD and RTLD_NODELETE. Switch to new pathfinder class, using (tmp_pathbuf_allocator): New class. (get_full_path_of_dll): Drop.

* strace: Don't print exception info for SetThreadName exceptionCorinna Vinschen2016-08-311-2/+6
| | | | | | | | | | The new functionality to set the thread name for debugging purposes creates exception debugging events. These are printed out when running strace. Since these exceptions have nothing to do with real exceptions but are, like breakpoint execptions, expected and non-fatal, don't print exception info for them.

* Fix passwd getting error 1265 when running on newer WindowsCorinna Vinschen2016-08-312-43/+52
| | | | | | | | | | | | | On Windows 8.1 and later, the NetUserChangePassword call apparently doesn't accept the usual "\\server" string anymore, but requires to use the "domain" instead, otherwise it emits en error code 1265, ERROR_DOWNGRADE_DETECTED. Since this is accepted by pre-8.1 as well, use the domain indiscriminately when calling NetUserChangePassword from passwd(1). While at it, do some minor cleanup in passwd.c.

* Fix off_t typedef on Cygwin64Yaakov Selkowitz2016-08-291-1/+1
| | | | | | | | | | While both long and long long are 64-bits on x86_64, they are distinct types, and long was used prior to commit 477463a2011ba81907a753df9ce7a71b6563db54. Changing this breaks the linking of previously compiled C++ functions with off_t arguments on 64-bit Cygwin with newly compiled code, as the mangling of long (l) and long long (x) differ.

* Fix SetThreadName with current gdbJon Turney2016-08-251-1/+6
| | | | | | | | | | | Wrap SetThreadName()'s call to RaiseException() in __try/__except/__endtry, so that if the attached debugger doesn't know about MS_VC_EXCEPTION (e.g. current gdb and probably strace as well) and continues exception processing, we ignore it, rather than dying due an unhandled exception. Also remove an unnecessary cast in the RaiseException() invocation. Signed-off-by: Jon Turney <jon.turney@dronecode.org.uk>

* Avoid crash when calling __localeconv_l with __C_localeCorinna Vinschen2016-08-241-0/+3
| | | | | | | | | __C_locale is const. Thus, overwriting the lconv values in __localeconv_l will try to write to a R/O region. Given the lconv values in __C_locale are initialized, there's no reason to write them in __localeconv_l at all. Just return &__C_locale.lconv. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Send thread names to debuggerJon Turney2016-08-237-1/+38
| | | | | | | | | | | | | | | | | | GDB since commit 24cdb46e [1] can report and use these names. Add utility function SetThreadName(), which sends a thread name to the debugger. Use that: - to set the default thread name for main thread and newly created pthreads. - in pthread_setname_np() for user thread names. - for helper thread names in cygthread::create() - for helper threads which are created directly with CreateThread. Note that there can still be anonymous threads, created by system or injected DLLs. [1] https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=24cdb46e9f0a694b4fbc11085e094857f08c0419
